You're really going to have to bring your "A" game to the panel board. My first question is whether you want to go the OCS route, or the DCO route. There are plenty of differences, pros, and cons of each. If you plan to go DCO, you'll need to bolster your letter of intent and your resume. Each cycle gets increasingly more difficult for selection. The panel boards for DCO rarely ask yoou questions about your experience, education, or expertise. They will ask you character type questions. For example, "You're a new ensign and division officer. The skipper gives you a task for your division to complete. While you are briefing your division on that task, the Chief says he knows a good way to get it done and starts to take over your spot light. What do you do?" There were lots of questions on integrity and ethics as well. "chief comes in drunk to work, what do you do?" stuff like that.
These questions are designed to weed out the people that will not make quality leaders. The reality is that nearly everyone who applies are equally as qualified to do the job of an Intel Officer. But not everyone has equal leadership abilities. For example, I was deployed with an air force TSgt who wanted to cross into the Navy Reserves as an 1835. He was a (AFSC) 1A8X2 working for AFSOC. He had a bachelor's degree in Intelligence Studies from AMU. and a MSSI from NIU. He was not selected for DCO. The selection odds may be at 15%, but the competition is incredibly steep. Prepare yourself now, get some LORs from flag/general officers, congressmen, or the like. Ensure that those LOR's reflect your high quality leadership capability with verifiable numbers and data. When you write your EPR, make sure there are numbers in there that reflect how many people you supervised and what they were able to accomplish under your direction.
I am still waiting for the results to come out for this past spring's DCO board. I am a 12 year IS1, five warfare pins, a bachelor's, master's, Eagle Scout, black belt, pilot's license, demonstrated leadership, special operations experience, etc... I'm not so optimistic that even with my qualifications that I will be accepted and awarded a commission.
